We are looking for self-motivated Developers to join our team and help deliver high-quality and impactful features to secure web applications. Your work will directly be stopping millions of cyber attacks on thousands of our customers. You will be working on our security suite, Astra, to build and maintain security software that runs on 1000's client websites. The job profile involves building scalable applications in Symfony and fine-tuning our CMS (WordPress/Magento etc.) plugins. You’ll be working closely with our CTO.

Dynamic Programming is mainly an optimization over plain recursion. Wherever we see a recursive solution that has repeated calls for same inputs, we can optimize it using Dynamic Programming. The idea is to simply store the results of subproblems, so that we do not have to re-compute them when needed later. This simple optimization reduces time complexities from exponential to polynomial. For example, if we write simple recursive solution for Fibonacci Numbers, we get exponential time complexity and if we optimize it by storing solutions of subproblems, time complexity reduces to linear.

Searching Algorithms are designed to check for an element or retrieve an element from any data structure where it is stored. Based on the type of search operation, these algorithms are generally classified into two categories:

  1. Sequential Search: In this, the list or array is traversed sequentially and every element is checked. For example: Linear Search.
  2. Interval Search: These algorithms are specifically designed for searching in sorted data-structures. These type of searching algorithms are much more efficient than Linear Search as they repeatedly target the center of the search structure and divide the search space in half. For Example: Binary Search.
